HI friends,
while defining Seismic Parameters in Staad using IBC, do we need to multiply the Ss, S1 parameters by g (=9.8 m/sec2) and enter the value or Staad automatically multiplies it?
since Ss & S1 are mapped seismic parameters defined as % of g.
For Example:
The Seismic Parameters for Riyadh(KSA) area are Ss = 0.05, S1 = 0.01 % of g. So when entering in Staad should we multiply these parameters by 9.81 (SI units) and enter as Ss = 0.49050, S1 = 0.098 or we can directly enter without multiplying.
Thanks in advance.
